ios - 无法解决崩溃 EXC_CRASH (SIGABRT)

Question

我两次为 iTunesConnect 发布我的应用程序，两次因为崩溃而被拒绝。

当用户点击 iPhone/iPad iOS 8.2 上的“联系人”选项卡时会发生这种情况，但我在模拟器或真实设备上对其进行了测试，但我不会出现此崩溃...

你能告诉我一些关于那个的事吗？

这是 崩溃日志 象征:

Answer 1

崩溃报告说问题出在第 20 行 (fbLikeButton)，我现在知道原因了:

« FBLikeControl 是一个预览功能，可能不会部署到 App Store。只有您的 Facebook 应用程序的开发人员和测试人员才能使用“赞”按钮。 »

因此应用程序崩溃并被 Apple 拒绝。
